I have the next query, but it doesn't update when I have but of a product with the same code in the table detallefacturas
UPDATE dbo.Kardex SET dbo.Kardex.SaldoDocumental = dbo.Kardex.SaldoDocumental + dbo.DetalleFacturas.Cantidad
FROM dbo.Kardex INNER JOIN dbo.DetalleFacturas ON
(dbo.Kardex.CodigoZofriID = dbo.DetalleFacturas.CodigoZofriID) WHERE dbo.DetalleFacturas.FacturaID = @FacturaID
for example.
